Manish Sisodia said while the formation of the political outfit will be announced later in the day today, its name will be announced on November 26.
Kejriwal too has hinted a delay in announcing the name when he said that it will be done after discussions.
"The movement which fought for a Jan Lokpal will now contest elections," Sisodia said, adding that November 26 was decided as the date for naming the party as the Constituent Assembly had adopted the Constitution on that day in 1949.
He alleged that rumours were being spread that no announcement will be made regarding formation of a political party.
